Hi I have just removed a light fitting, which has revealed 3 main cables, all cables have a black, red and earth wire. This is in my kitchen which has a extractor fan (which has never worked) one of the cables had the red wire wired to the light but the black and earth had been cut short and tucked away so not wired with the two other full cables. Do I just wire all the live, neutral and earth wires together in the terminals? Any help is appreciated. I’ve attached pictures of the wires and new light fitting. Thanks
